Problem: curl certificate error (--ssl-no-revoke) —— Trove problem library

What you will run into

Using curl on Windows to download/install related scripts reports certificate errors (SSL certificate problem / revocation-related). The script never runs; it dies on the certificate first.

Why this happens

Windows certificate revocation checks can fail in some network/proxy environments; self-signed or proxy certificates aren't trusted by curl, so TLS validation fails.

TLS validation is actually two layers: chain validation (is the certificate issued by a trusted CA) + revocation checking (has the certificate been revoked).

Windows curl enables revocation checking by default, while Linux disables it by default — that platform difference is the root of this whole issue.

Revocation checking must reach CRL/OCSP services over the network, which often fails in proxy/restricted networks, and Windows then kills the connection.

--ssl-no-revoke only skips the revocation layer; it does not affect chain validation — it will not help when the chain itself is invalid (e.g.

self-signed). In that case the right move is to add the certificate to the trust store, not to use -k to disable all validation.

Step by step

1. Add --ssl-no-revoke for install-script scenarios — Required

A Windows curl argument that skips the certificate revocation check (CSDN 2026-01 case path).

2. Or install via the pip path — Required

pip install deepcode-hku

pip's truststore handles certificates more reliably.

3. Work inside a virtual environment — Required

python -m venv .venv && .venv/bin/pip install deepcode-hku

Avoids system-level changes.

How to confirm it works

Download/install completes (expected shape):

curl --ssl-no-revoke ... -> file fully downloaded
pip install deepcode-hku -> Successfully installed

No more SSL certificate problem.

Other environments

Symptom

Using curl on Windows to download/install related scripts reports certificate errors (SSL certificate problem / revocation-related).

Cause

Windows certificate revocation checks fail in some network/proxy environments; self-signed or proxy certificates aren't trusted by curl.

Solution

1. Add --ssl-no-revoke for install-script scenarios (a Windows curl argument).
2. Or install via the pip path (pip's truststore handles certificates more reliably).
3. Recommended to work inside a virtual environment to avoid system-level changes.
